The DF of a two-dimensional, non-axisymmetric disk

class galpy.df.evolveddiskdf(initdf, pot, to=0.0)

Class that represents a diskdf as initial DF + subsequent secular evolution

__init__(initdf, pot, to=0.0)

NAME:

__init__

PURPOSE:

initialize

INPUT:

initdf - the df at the start of the evolution (at to) (units are transferred)

pot - potential to integrate orbits in

to= initial time (time at which initdf is evaluated; orbits are integrated from current t back to to) (can be Quantity)

OUTPUT:

instance
